If you're on a modern system or at least having TPM 2.0 with secure boot enabled in bios settings. You can easily switch to windows 11.
It's not recommended to be used on older machines.although it can be installed with the bypass method yet not recommended at all.
Windows 10 is way better and much lighter than Windows 11. Better RAM management, useful and to-the-point features in 10 than 11. I have used Windows 11 on my office 11th Gen i5 and then on my personal 9th Gen i5 Gaming laptop. Both times I experienced delays and slow responses. Both systems are now reverted back to Windows 10.
Hesitantly switched to windows 11 but im so thankful I did. Fkin awesome lookin window and seemingly no performance difference, i would even say it feels smoother. Idk why people are still using windows 10
